Patent number: 10434845Abstract: An opening formed in a window glass pane is smoothly opened and closed by a slide panel slidingly driven along a panel surface of the window glass pane and along a direction orthogonal to the panel surface. The guide rail (4) is provided with a pin guide groove (27) including a groove main portion (27a) and a groove extension portion (27b). A slider (20) is provided with a pin drive groove (30) extending in a direction crossing the panel surface. The slide panel is provided with at least one pin (16) projecting into the pin drive groove and the pin guide groove so that the slide panel is positioned in a closed position when the pin is positioned in the groove extension portion, and in an open position when the pin is positioned in the groove main portion.Type: GrantFiled: August 22, 2017Date of Patent: October 8, 2019Assignee: Yachiyo Industry Co., Ltd.Inventors: Akira Murasawa, Tatsuaki Uehara
